Everything looks like a 3-D movie!

Turned on the set one day and the images are sorta color separated and it looks like a 3-D movie without the glasses on; any ideas what this might be?

How do you get the screen to converge after replacing parts?

My magic focus wont work?

Is there a service menu?

Thanks

Replace convergence IC's IK04 = STK392-150 and IK05 = STK392-110. Also check resistors RK42,RK46,RK50,RK54,RK58,RK62 for burnt/discolored.

Hi,
The problem is your convergence circuit board gone bad. This is commonly caused by shorted/open IC on that board. First try to spot if there is a bad solder joints and resolder it. If nothing replaced the convergence IC. Also check the resistors around.
Hope it may help you.
Have a nice day!
Thanks for using Fixya.

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.

Strong colors, specifically those in the red


it seems you are experimenting a light engine problem.This is how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact maker or look for your light engine online.

Sony Hi-Scan 1080i 52" projection TV colors won't converge


No you will need to repace compents. Do you know how to solder and use a meter? If so I can assist you with the repair. If not you will need a repairman, he will cost you about $300-$500 for the fix.

Have you checked out the HDMI cable? A composite cable failure can cause the same.
